| Abstract: | The working state of a 22 kW DC motor to drive an air-blower is analyzed. A constant speed regulating system using a single IGBT as a high-power switch component is introduced. The DC PWM signal control and its principle to drive a circuit are analyzed. The over-voltage protection circuit, over-current protection circuit and their parameters are discussed. Results of constant current speed regulating experiment in a large voltage range are given. |
